this is the kind of thing that the GnomeCanvas widget is for. it renders
into an RGBA buffer and then draws that to the on-screen drawable. it
has primitives for lines, polygons, text etc.

people castigate the canvas object mostly because of the low level
drawing engine behind it (libart_lgpl). its still very fast, and even
though the canvas widget is sort of dead, it appears reasonable to
believe that its API will continue to exist in a very similar form when
it is resurrected and back by cairo (an alternate rendering library
which can potentially use h/w acceleration if appropriate).
